Robust metal structure Overview
IR-S is a gas sensor based on the principle of infrared absorption.
Compared with traditional gas sensors, it has the advantages of
good stability, strong selectivity, no oxygen dependence, wide
detection range, long lifespan, long maintenance period, and strong
anti-interference ability.
IR-S adopts a low-power processor, imported light source and
dual-channel detector. It controls the overall power consumption
while maintaining a constant sensor working current to ensure that
the power supply circuit is not affected by current shock, ensuring
the high efficiency, high accuracy and stable and reliable
operation of the sensor data processing.
IR-S has digital signal output and analog voltage output, which is
convenient for customers to choose applications. In addition,
IR-S/CO2 provides customers with zero-point calibration and
sensitivity calibration commands. At the same time, there are
multiple baud rates and voltage ranges available for customers to
choose.
Application
Industrial or mining gas concentration transmitters
Industrial or mining portable gas analyzers
Meteorology, agriculture, environmental air quality monitoring
Air quality monitoring in public places
Customizable measurement for other gases such as CO, SF6, etc.
